I usually use 100% IPA to wash my RK05 packs...
I don't let acetone get near my stuff. It probably will remove the
laquer. Nice prep if you want to apply a new coating to your disk.
I do it like Klemens: Scrub, scrub, scrub. The black spots MUST be
removed. Important not to lay the disk onto a hard or somehow grain
contaminated surface while scrubbing.
BTW: The RK05 manual explicitly warns from WATER on the disks. You
should not spit (i.e. blow!) onto the surfaces as water is said to
dissolve the coating.

We clean our RK05 disks in a very robust way:
with cheap burning spirit
and paper towels. ... We rubbed away thick black traces from occasional
head crashes and we never removed the oxide coating with this torture.
I am about to get a large batch of RK05 packs, so I am interested in the
details of this.
First, what is 'burning spirit'? (I assume this is a straight translation
into English of some German term, but not knowing German... :-) After poking
around with Google for a while (hampered no little by the fact that it's the
name of a band, and also a term in World of Warcraft :-), it seems like it
might be acetone?
